Skycow:

A fleet of bio-engineered flying cows that form a line in the sky and fly across America. (And possibly Canada, but the procedure is a little different.)

At a certain time of day, every day, the people are supposed to come out of their house. They stand out in their yard with a glass (a plastic bag in Canada) or two and the cows shoot milk down into the empty glasses.

Of course, there would have to be pilots for the cows, at least at first. They would eventually replace the pilots with a computer backpack for each cow. It would use GPS to aim the udder at its intended target (the glass or bag) and regulate the amount of milk dispensed to each target.
